SPRING-GUN.

Specification of Letters Patent.

Patented June 25, 1912.

Application filed. February 19, 1912. Serial No. 678,741.

To all whom it may concern:

Be it known that I, GEORGE PREIS, a sub ject of the Emperor of Russia, and a res1- dent of Cambridge, in the count-y of Mid-' dlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Spring-Guns, of which the following is a full and exact description.

This invention, while adapted for shooting any form of small missile, as marbles, beans and the like, is specifically designed for firing fan-like objects which take the form of birds after being discharged into the air.

Referring to the drawings forming part of this specification, Figure 1 is a side elevation of a spring gun made in accordance with my invention. Fig. 2 is a central longitudinal section of a portion of the gun barrel. Fig. 3 is a similar section of another portion of said barrel. Fig. 4 is a detail view of the spring setting handpiece. Fig. 5 is a sectional end-view of the same, showing the gun barrel in cross section. Fig. 6 is a cross section of the gun barrel. Fig. 7 is a longitudinal section of the outer end of the spring containing barrel.

In the drawings, the reference numeral 1 designates the stock; 2, the barrel, and 3 the trigger of the gun. Longitudinally movable within said barrel is the plunger 4 the suddenthrow of which impels the missile placed in the barrel. For the actuation of this plunger, a spiral tension spring 5 is located in the spring barrel 6 located parallel with the barrel 2 and of substantially equal length. Said spring is terminally attached to the outer end of the barrel 6 by means of the cap 7 having a notched stem 8 engaged by the spring; and at its other end is attached in a similar manner to the slide 9 connected with the plunger 4, as shown in Figs. 7 and 2. By drawing said slide toward the stock 1, said plunger is put in a position for loading the gun, and said spring is put into a state of tension, so that when the slide is released, the plunger shoots forward and any object in front thereof is impelled from the gun barrel with considerable velocity. For thus moving said slide and tensioning the spring, a hand piece 10 is provided which is slidable along the spring barrel 6 and is kept from turning thereon by means of the curved wing 11 loosely titting the surface of the gun barrel 2, as shown in Figs. 1 and 5. A doubled wire 12 having its ends fixed in said hand piece, passes along both sides of the slide 9 with its looped part behind the same. Said looped'part 13 comes within a recess 14 in said slide, as shown in Figs. 2 and 3, and is locked therein by a dog 15 controlled by a light spring 16. When, now, the hand piece 10 is pressed rearward, its looped wire meets said dog and carries with it the slide and plunger, and tensions the spring. When the slide reaches the desired position, its notch 17 (Fig. 3) is engaged by the detent 19 of the trigger 3, and at the same time the leaf spring 20 of said trigger presses upward against the tail of said dog to throw the latterout of its engagement with the looped wire. The trigger being pulled, the detent 19 releases the slide 9 and the latter and the plunger fly forward and fire the introduced missile; the depressed position of the dog keeping it from meeting the looped wire and throwing the hand piece forward with the same. The forward throw of the parts "is limited by the termination of the slots 21, 22 in the barrels 2 and 6, in which slots the slide 9 plays. At the end of these slots is also a stop 23 which binds the two barrels together at such point, as shown in Fig. 3 and also in Fig. 6, the latter view disclosing the holes through which the wire ends pass. Said stop is so located that when the slide 9 reaches it at the extremity of its forward throw, the wire loop 13 will be able to enter the recess 14 and be locked therein by the dog 15 when or just before the hand piece 10' is carried forward to its stop 25. WVhen the hand piece has thus been slid forward, and is then forcibly drawn rearward, the slide and plunger will be brought back and reset for another firing of the gun.

hat I claim as my invention and for which I desire Letters Patent is as follows, to wit 1. A spring gun comprising two parallel barrels, a plunger in one thereof, a tension spring in the other barrel, a slide connecting said plunger and spring, both barrels being slotted for the passage of said slide, means for forcibly moving said slide and tensioning said spring, a dog carried by the slide adapted to be engaged by said means and to release the latter when the slide is in its set position, and a trigger for holding the slide in its set position.

2. A spring gun comprising two parallel barrels, a plunger in one thereof, a tension spring in the other barrel, a slide connecting said plunger and spring, both barrels being its set position.

3. A spring gun comprising two parallel barrels, a plunger in one thereof, a tension spring in the other barrel, a slide connecting said plunger and spring, both said barrels being slotted for the passage of said slide, a hand piece slidable on the springcontaining barrel, a looped wire having its ends held by said hand piece and embracing said slide, a dog carried by said slide and adapted to lock said looped wire in the control of said slide, and a trigger adapted for holding said slide in its set position, said dog being adapted to release said looped- "being slotted for the passage of said slide,

and a hand piece adapted for setting said slide and connected part-s, said hand piece being loosely pierced'by the springcontaining barrel and having a concave surface loosely fitting the exterior of the other barrel. 7

In testimony that I claim the foregoing invention, I have hereunto set my hand this 17th day of February, 1912.
